LULU-043 - 「絶対にコスるだけだからね！」両親が不在の3日間、可愛すぎる妹の股間に素股で何度も兄のデカチンを擦りつけたら…ヌルッと生挿入！焦らされ続きで溜まった性欲我慢マ○コは即イキ連発！禁断の近親相姦ナマ中出し！ 泉りおん

Both the actress and the actor give such natural performances; it feels incredibly real. I mean, once you get to that point, there's no way you're not going to go all the way.

It never ends with just rubbing, does it? As a fan of 'sumata' (thigh sex), I'd love to see more scenes where they just lose control and finish right there.

If they're going to market this as a 'realistic AV,' I wish they had kept it more realistic. Even if they're close, what sister wouldn't feel at least a little disgusted by her brother rubbing himself against her? Unless they add some kind of aphrodisiac item or a 'promiscuous' character setting, it just ends up being another generic incest-romance flick.

Rion is just unconditionally cute. She climaxes multiple times during internal sex, but she does the same during thigh-sex, so it feels like a huge win to get both. The plot seems loosely scripted with ad-libbed dialogue, so Hayashi's comments and actions feel a bit random, but their banter is actually pretty funny. It's amazing how Hayashi can stay erect while having casual, non-sexual conversations. Plus, he does a lot of handheld filming, and his ability to capture the right angles while having sex is phenomenal. The fact that Rion struggles during fellatio because he's too big is just part of the charm. (Omitted: Timeline details)

Izumi Rion has such a thick, curvy lower body, which is the best. It felt like this work really leaned into that charm with lots of zooms on her lower body, face-to-face thigh-sex, and doggy-style angles. It was very helpful.
